Is it a not easy or difficult exercise?
I repeat it from Life Lines pre-intermediate, unit 13:
It was 1973 and Sarah Simms was a happy 19-years-oldõ?Ư
Two days earlier, Sarah had been in a car crash. The accident had erased twenty years of her memory. It was now 1993, but for Sarah it was 1973, and she was a teenager. Sheõ?Td forgotten the twenty years in between.
In those twenty years, Sarah has got married. (In 1973 she hadnõ?Tt met her husband.)õ?Ư
End, and now itõ?Ts time to write the question:
1. Say whether these thongs had or hadnõ?Tt happened to Sarah in 1973: hair/ turn yellow
2. Complete these sentences. Put the verbs in brackets into past tense or the past perfect tense: Her hair õ?Ư(turn) gray and she õ?Ư (not like) that.

Please let me know how you can answer this intelligent. I repeat again: thatõ?Ts a not easy or difficult exercise. In my class, there was an argument for this.
